Description
This presentation collects experiences from tests of ATLAS end cap
SCT
modules using infrared semiconductor laser on 1060 nm wavelenght.
Sophisticated method of focusing was developed. Timing and interstrip
properties of modules were measured.
Tests of silicon sensors simulate real experimental conditions and
check
important detector properties. Laser tests have good time and space
description, but photons generate electron-hole pairs in silicon
bulk via
different mechanism. Detailed discusion about usability of laser
test for
particle detectors is presented.
Laser tests are extremely useful for tuning individual sensor and
readout
settings to find optimal working parameters. Furthermore they are
good for
comparison between the same type of detectors with exactly the same
top
surface properties.
